As technology evolves, layers upon layers of abstraction are built on it until inner complexity turns transparent to those using it. The user is therefore able to find more sophisticated uses for it than would have been possible in its nascent stages.
Often a generation passes between the birth of a new technology and the attainment of wizard driven widget-ization nirvana. The tech geezer knows the innards of technology that is now bleeding edge and yet is not quite the alpha-geek.
Quite like how a chemist is not a perfumier -abstraction and imagination are no less important than knowledge in the raw.
